A Model of Local Heat Transfer between a Fluidized-Bed and an Immersed Horizontal Tube

With the experimental data of particle-wall contact frequency and contact time, along with the data of the increasing rate of local convective heat transfer of the gas flow disturbed by particle movement, the previous single-particle model has been improved and the varying local heat transfer coefficients around an immersed horizontal tube have been predicted. The prediction shows good agreement with experimental data.
